CENTRAL FILES
DWR SECTION
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the eight stormwater outfalls located at Cree, Inc., 4600 Silicon Drive, Durham, Durham
County, North Carolina. The analytical reports were received from the laboratory on November 23,
2018. ESC Lab Sciences (NC ID #ENV 375) conducted the analyses which completes the second 2018
semi-annual testing requirements for the Silicon Drive site.
Discharge samples were collected at outfall #1, #2, #3, #5, #6 and #7. No sample was collected at
outfall #4 due to absence of flow, and is recorded as NO DISCHARGE. For the sampled outfalls,
and as in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark
values listed in Table 3 of section 11.13 of our stormwater permit for outfall #7 (Cu) and outfalls #2 and #5
(Zn). In September 2014, Cree was granted an exemption from the requirement to continue following
Tier Two and Tier Three response actions as stated in Section B of the stormwater permit for these
parameters. Cree will continue to monitor these levels throughout the next semi-annual testing period
and report any success in eliminating the elevated levels.
In addition, the values for Cu reported above the benchmark levels at outfalls #1, #2, #3, #5, and #6,
and the Zn values reported above the benchmark levels at outfall #1 and #3 during the spring 2018
event (initiating Tier One response actions) have returned to normal ranges at this collection event.
Please contact me at 919-407-6101 if you need additional information.
Sincerely,
Donna Lazzari
Environmental Manager

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition ofTotat Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility
subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR
469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring maybe waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."

GLOSSARY OF TERMS ONE LAB, NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
Cp
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
2Tc
MDL
Method Detection Limit.
NO
Not detected at the Reporting Limit (or MDL where applicable).
rq
RDL
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
FCn]
SDG
Sample Delivery Group.
u
Not detected at the Reporting Limit (or MDL where applicable).
El
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
F
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 Is used in this field, the
result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the taboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
AI
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
FSC1
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or 'SOL"
Result
(Below Detectable Levels), The Information In the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
A brief discussion about the Included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Oc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory Is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had contras or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sri
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (5s)
This section of the Analytical Report defines the specific analyses performed for each sample ID, Including the dates and
times of preparation and/or analysis.
Qualifier
Description
J
The identification of the analyte is acceptable; the reported value is an estimate.
P1

RE: Stormwater Discharge Outfall (SDO) Monitoring Report Dvvr.? SECTION
Cree, Inc., 4600 Silicon Drive, Durham, Durham County, North Carolina
General Stormwater Permit No. NCG0300001COC NO. NCG030433
January — June 2018, SDO #1, #2, #3, #3A, #4, #5, #6 and #7
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the eight stormwater outfalls located at Cree, Inc., 4600 Silicon Drive, Durham, Durham
County, North Carolina. The analytical reports were received from the laboratory on May 15, 2018. ESC
Lab Sciences (NC ID #ENV 375) conducted the analyses which completes the first 2018 semi-annual
testing requirements for the Silicon Drive site.
Discharge samples were collected at outfall #1, #2; 0, 0A, #5, #6 and #7. No sample was
collected at outfall #4 due to absence of flow, and is recorded as NO DISCHARGE. For the
sampled outfalls, and as in previous reports submitted to DEQ, levels for copper and zinc are above the
benchmark values listed in Table 3 of section 11.13 of our stormwater permit for outfalls #1, #2, #3A, #5,
#6, #7 (Cu) and outfalls #1, #2, #3, #5 (Zn). In September 2014, Cree was granted an exemption from
the requirement to continue following Tier Two and Tier Three response actions as stated in Section B
of the stormwater permit for these parameters. Cree will continue to monitor these levels throughout
the next semi-annual testing period and report any success in eliminating the elevated levels.
In addition, the values for pH reported below the benchmark levels at outfall #5, and the TSS values
reported above the benchmark levels at outfall #1 during the winter 2017 event (initiating Tier One
response actions) have both returned to normal ranges at this collection event.
Please contact me at 919-407-6101 if you need additional information.
Sincerely,
nna Lazzari

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12, for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31)_
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."

RE: Stormwater Discharge Outfall (SDO) Monitoring Report
Cree, Inc., 4600 Silicon Drive, Durham, Durham County, North Carolina
General Stormwater Permit No, NCG0300OO/COC NO. NCG030433
July - December 2017, SDO #1, #2, #3, #3A, #4, #5, #6 and #7
To Whom It May Concern:
4600 Silicon Drive
Durham, NC 27703 USA
Main: [phone]
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the eight stormwater outfalls located at Cree, Inc., 4600 Silicon Drive, Durham, Durham
County, North Carolina. The analytical reports were received from the laboratory on December 9, 2017.
ESC Lab Sciences (NC ID #ENV 375) conducted the analyses which completes the second 2017 semi-
annual testing requirements for the Silicon Drive site.
Discharge samples were collected at outfall #1, #2, #5, #B and #7. No samples were collected at
outfalls #3, 0A and #4 due to absence of flow, and are recorded as NO DISCHARGE. For the
sampled outfalls, and as in previous reports submitted to DEQ, levels for copper and zinc are above the
benchmark values listed in Table 3 of section 11,13 of our stormwater permit for outfalls #002 (Cu) and
outfalls #001, #002 (Zn). In September 2014, Cree was granted an exemption from the requirement to
continue following Tier Two and Tier Three response actions as stated in Section B of the stormwater
permit for these parameters. Cree will continue to monitor these levels throughout the next semi-
annual testing period and report any success in eliminating the elevated levels.
Additionally, outfall #5 tested below the benchmark level for pH at 5.78 and outfall #1 tested above the
benchmark level for Total Suspended Solids (TSS) at 177 mg/L as outlined on page 6, Table 3 of the
general permit. In accordance with this exceedance, Cree has instituted Tier One actions to include the
following:
Tier One
If the first valid sampling results are above a benchmark value, or outside of the benchmark range, for
any parameter at any outfall:

1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential and select the specific source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring
concentrations within the benchmark range. a
4. Implement the selected actions within two months of the inspection.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedance, the inspection date, the personnel conducting the inspection, the
selected actions, and the date the selected actions were implemented.
DMR results from this recent testing for NCG030433 are included for review. Cree's next semi-annual
test period will occur January -July 2018 at which time pH and TSS will be re -analyzed for comparison
to the earlier benchmark exceedances.
Please contact me at 919-407-6101 if you need additional information.
Sincerely,
Donna Lazzah

RE: RETEST OF OUTFALLS FROM JUNE SAMPLING EVENT, 1ST SEMI-ANNUAL
TESTING
Stormwater Discharge Outfall (SDO) Monitoring Report
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030433
January- June 2017, SDO #3, 0A, #4, #5, #6 and #7
To Whom It May Concern;
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for a re -test of remaining outfalls listed as NO DISCHARGE from Cree's earlier report on the
seven stormwater outfalls located at Cree, Incorporated, 4600 Silicon Drive, Durham, Durham County,
North Carolina submitted for July 5, 2017. The retest analytical reports were received from the
laboratory on September 20, 2017, ESC Lab Sciences (NC ID # ENV 375) conducted the analyses for
the retest of the outfalls not sampled in the previous period for the 1" 2017 semi-annual testing
requirements.
No samples were collected at outfalls #3, #3a, and #4 due to absence of flow, and are recorded as
NO DISCHARGE on 9/12/2017. For the sampled outfalls, and as in previous reports submitted to
DEQ, levels for copper and zinc are above the benchmark values listed in Table 3 of section 11.13 of our
stormwater permit for outfalls 4005, #006, and #007 (Cu) and outfalls #005, #007 (Zn). In September
2014, Cree was granted an exemption from the requirement to continue following Tier Two and Tier
Three response actions as stated in Section B of the stormwater permit for these parameters. Cree will
continue to monitor these levels throughout the next semi-annual testing period for 2017 and report any
success in eliminating the elevated levels.
DMR results from this recent testing for NCG030433 are included for review.

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of any knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stotmwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan." /

CASE NARRATIVE ONE LAB, NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOO)
values reported for environmental samples have been corrected for the dilution factor used in the
analysis. All radlochemical sample results for solids are reported on a dry weight basis with the
exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method
and Batch Quality Control are within established cr4eria except where addressed in this case narrative,
a non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data.

RE: Stormwater Discharge Outfall(SDO) Monitoring Report CWR SECTION
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030433
January- June 2017, SDO #1, #2, #3A, #4, #5, #6 and #7
To Whom It May Concern;
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the seven stormwater outfalls located at Cree, Incorporated, 4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on July 5,
2017. ESC Lab Sciences (NC ID # ENV 375) conducted the analyses for the first 2017 semi-annual
testing requirements for the Durham site.
Discharge samples were collected at outfalls #1 and #2. No samples were collected at the other
outfalls due to absence of flow, and are recorded as NO DISCHARGE. For the sampled outfalls,
and as in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark values
listed in Table 3 of section I1.13 of our stormwater permit for outfalls #002 (Cu) and outfalls #001, #002
(Zn). In September 2014, Cree was granted an exemption from the requirement to continue following
Tier Two and Tier Three response actions as stated in Section B of the stormwater permit for these
parameters. Cree will continue to monitor these levels throughout the next semi-annual testing period
for 2017 and report any success in eliminating the elevated levels.
In addition, the value for pH reported below benchmark levels at outfall #002 during the fall 2016 event
(initiating Tier One response actions) has returned to normal range at this collection event.
DMR results from this recent testing for NCG030433 are included for review; Cree will obtain samples
at the next acceptable rain event for the remaining outfalls and submit to DEQ at that time.
Sincerely,
eonna Lazzarz

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31),

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."

General Stormwater Permit No. NCG030000/COC NO. NCG030433
July- December 2016, SDO #1, #2, #3A, #4, #5, #6 and #7
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the seven stormwater outfalls located at Cree, Incorporated, 4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on December
23, 2016. ESC Lab Sciences (NC ID # ENV 375) conducted the analyses which completes the second
2016 semi-annual testing requirements for the Durham site.
As in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark values
listed in Table 3 of section I1.13 of our stormwater permit for outfalls #001, #002, #005, #006, and #007
(Cu) and outfalls #001, 4002, and #005 (Zn). In September 2014, Cree was granted an exemption from
the requirement to continue following Tier Two and Tier Three response actions as stated in Section B
of the stormwater permit for these parameters. Cree will continue to monitor these levels throughout the
next semi-annual testing period for 2017 and report any success in eliminating the elevated levels.
In addition., the value for pH was below benchmark level at outfall #002 during the sampling event;
Cree will therefore initiate Tier One activities as described in Section II, Part B, page 3 of General
Permit NCG030000, and will re-evaluate this parameter in our first semi-annual testing period in 2017.
DMR results from this recent testing for NCG030433 are included for review and completes Cree's
second semi-annual stormwater testing requirement for 2016 for the Durham site.
Please contact me at 919-407-6101 if you need additional information.
Sincerely,
Donna LazzGLL

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the E
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOG) values reported for environmental samples have been corrected for the dilution factor used in the rTcl
analysis. All Method and Batch Ouality Control are within established criteria except where addressed
in this case narrative, a non-conformance form or properly qualified within the sample results. By my ❑
digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the 35s
laboratory as having the potential to affect the quality of the data have been Identified by the
laboratory, and no information or data have been knowingly withheld that would affect the quality of the
data.

Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the seven stormwater outfalls located at Cree, Incorporated, 4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on July 14,
2016. Meritech. Laboratories (Certificate #165) conducted the analyses which completes the first 2016
semi-annual testing requirements for the Durham site.
As in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark values
listed in Table 3 of section II.B. of our stormwater permit for outfalls #001, 002; 003a, 004a 005, 006,
and 007 (Cu) and outfalls #001, 002, 004a, 005, and 006 (Zn). In September 2014, Cree was granted an
exemption from the requirement to continue to follow Tier Two and Tier Three response actions as
stated in Section B of the stormwater permit. Cree will continue to monitor these levels throughout the
next semi-annual testing period for 2016 and report any success in eliminating the elevated levels.
DMR results from this recent testing for NCG030541 are included for review and completes Cree's first
semi-annual testing requirement for 2016 for the Durham site.

RE: Stormwater Discharge Outfall (SDO) Monthly Monitoring Report
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030433
June- December 2014, SDO #1, #2, #3A, #4A, #5, #6 and #7
To Whom It May Concern:
Please find enclosed the semi-annual Stormwater Discharge Monitoring Reports (one original and one
copy) for the seven stormwater outfalls located at Cree, Incorporated, 4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on
December 23, 2014. Meritech Laboratories (Certificate ##165) conducted the analyses which completes
the 2014 semi-annual testing requirements for the Durham site. Please note that outfalls SDO-003 (no
flow) and SDO-006 (no access) were not sampled at this time.
These results follow the actions implemented as Tier 2 response for elevated copper and zinc levels at
the facility. Notification that Cree, Inc. intended to implement the actions required as a Tier 2 response
was sent to the DWQ in January, 2014 based on the results of the Stormwater sampling conducted in
December, 2013. Additional samples were obtained in February, 2014. As Cree has demonstrated
that no copper or zinc is used in its manufacturing process and has no clear source for the
contamination, DWQ has granted relief from further Tier response testing on September 24,
2014, and has instructed Cree to resume normal storm water testing for the 2Id semi-annual
testing period for 2014 through 2017(see attached document). DMR results from this recent
testing are included for review and completes Cree's semi-annual testing requirement for 2014.
Subsequent testing continues to report values for copper and zinc above the benchmark values listed in
Table 3 of section II.B. of our permit for outfalls # 1,2,5, and 7 (Cu and Zn), and 4a(Zn), and within
limits for all other permit parameters. Cree will continue to monitor these levels throughout the semi-
annual testing periods for 2015 and report on any success to eliminate the elevated levels.
Please contact me at 919-407-6101 if you need additional information.

Dear Ms. Lazzari:
John E. Skvada, III
Secretary
In response to your discussions with NCDENR Land Quality Section staff, concerning multiple
exceedances of the benchmark values for zinc and copper, Dave Parnell of the Land Quality
Section - Stormwater staff, conducted a compliance evaluation inspection (CEI) on April 8,
2014. The inspection was conducted to determine compliance with the conditions of your
NPDES NCG030433 Stormwater Permit and to discuss any actions that have been or could be
taken to identify and eliminate potential sources of Zinc and Copper related to facility
operations.
Keep in mind that benchmark exceedances are not limit violations or violations of permit
conditions, however, you are obligated to Follow the tiered response actions outlined in your
permit. At the time of the inspection, your facility was found to be in compliance with the
tiered response actions and other conditions of the permit. During the inspection, you are
reported to have relayed to Mr. Parnell that you have been unable to determine the source of
the higher levels of the metals, found at the Silicon Drive outfalls. It is notable in this case,
that CREE does not use copper or zinc in the manufacturing processes and the facility has
conducted extensive reviews of your site for external sources of the metals. Your diligence in
attempting to determine and eliminate the zinc source and your continued communication
with Raleigh Regional Office staff is commendable and is documented back to the April 8
compliance evaluation inspection.

the form of collapsed Tier 2-Tier 3 response. Upon receipt of this letter, CREE - Silicon
Drive, may resume the permit specified semi-annual analytical monitoring for the remainder
of the current permit term - which ends October 31, 2017. This decision applies only to the
zinc and copper benchmarks. A benchmark exceedance of any other parameter listed in
your permit will trigger the tiered response actions as described in your permlL
You must notify this office, in writing, within five business days if you become aware of any
significant source of zinc or copper at your facility, that has the potential to be exposed to
stormwater. The relief granted in this letter is contingent upon the current industrial
practices at CREE. If industrial practices change and zinc & copper does become a significant
Stormwater exposure risk, then this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response or other actions that may be warranted by the
new set of circumstances.
Retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit.
Should you have questions or comments regarding the CEI or this letter, please contact Dave
Parnell at [phone] or [e-mail].

To Whom It May Concern:
9°° O*Vlk
Please find enclosed the monthly Stormwater Discharge Monitoring Reports (one original and one
copy) for the seven storrnwater outfalls located at Cree, Incorporatod, .4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on June 9,
2014. Meritech Laboratories (Certificate #l163) conducted the analyses.
These results are following the actions that have been implemented as a Tier 2 response for elevated
copper and zinc levels at the facility. Notification that Cree, Inc. intended to implement the actions
required as a Tier 2.response was sent to the DWQ in January,,2014 with the results of the stvrmwater
sampling conducted in December, 2013. Additional samples were obtained in February, 2014 and
again for this report in May, 2014.
The Cree Durham site received an annual spw3 inspection by David Parnell. on April S, 2014.
Suggestions floor that inspection have been implemented, and additional actions have been taken to
identify and limit the amount of copper and zinc in the storm water. However, subsequent testing
continues to report values for copper and zinc above the benchmark values listed in 'r able 3 of section
II.B. of our permit for all outfall discharge monitoring points with the exception of outfalls #6 and #7
for zinc. -
As test.results continue at elevated levels for copper and zinc for four successive sampling periods,
Cree is requesting a meeting with DWQ to determine the best path forward to address these elevated
values.

Please contact me at 919-407-6101 if you need additional information.

Relief from Advanced Tier Response

Dear Ms. Lazzari:
John E. Skvarla, Ill
Secretary
In response to your discussions with NCDENR Land Quality Section staff, concerning multiple
exceedances of the benchmark values for zinc and copper, Dave Parnell of the Land Quality
Section - Stormwater staff, conducted a compliance evaluation inspection (CEI) on April 8,
2014. The inspection was conducted to determine compliance with the conditions of your
NPDES NCG030433 Stormwater Permit and to discuss any actions that have been or could be
taken to identify and eliminate potential sources of Zinc and Copper related to facility
operations.
Keep in mind that benchmark exceedances are not limit violations or violations of permit
conditions; however, you are obligated to follow the tiered response actions outlined in your
permit. At the time of the inspection, your facility was found to be in compliance with the
tiered response actions and other conditions of the permit. During the inspection, you are
reported to have relayed to Mr. Parnell that you have been unable to determine the source of
the higher levels of the metals, found at the Silicon Drive outfalls. It is notable in this case,
that CREE does not use copper or zinc in the manufacturing processes and the facility has
conducted extensive reviews of your site for external sources of the metals. Your diligence in
attempting to determine and eliminate the zinc source and your continued communication
with Raleigh Regional Office staff is commendable and is documented back to the April 8
compliance evaluation inspection.

Based onthe aforementioned items, DENR Land Quality Section is granting regulatory relief in
the form of a collapsed Tier 2-Tier 3 response. Upon receipt of this letter, CREE - Silicon
Drive, may resume the permit specified semi-annual analytical monitoring for the remainder
of the current permit term - which ends October 31, 2017. This decision applies only to the
zinc and copper benchmarks. A benchmark exceedance of any other parameter listed in
your permit will trigger the tiered response actions as described in your permit.
You must notify this office, in writing, within five business days if you become aware of any
significant source of zinc or copper at your facility, that has the potential to be exposed to
stormwater. The relief granted in this letter is contingent upon the current industrial
practices at CREE. If industrial practices change and zinc & copper does become a significant
stormwater exposure risk, then this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response or other actions that may be warranted by the
new set of circumstances.
Retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP] or permit.
Should you have questions or comments regarding the CEI or this letter, please contact Dave
Parnell at [phone] or [e-mail].

Raleigh, NC 27609
RE: Notification of Release
Cree, Inc., Durham, North Carolina
NPDES Permit No. NCG 030000, COC No. NCG030433
Dear Mr. Smith,
ti' h1 Z
MAY 15 i012
As required by NPDES Storm Water Permit NCG03000, Paragraph 8, Part 111, Page 10 of
11, Cree, Inc. is providing this written submission regarding the release of oil that
occurred at its facility located at 4600 Silicon Drive, Durham, Durham County, North
Carolina. This release was reported to you via phone on May 9, 2012, at approximately
1:40 PM.
RELEASE DESCRIPTION AND REPORTING ACTIVITIES
On May 7, 2012, Cree personnel discovered lubricating oil had leaked from a piece of
equipment that is maintained and controlled by our vendor, AirGas. The leak resulted in
the release of oil that entered one of Cree's storm water drains and was dispersed on the
ground near the drain exit. The affected area is completely within Cree's property
boundaries, and we have no reason to believe that there has been any surface water or
groundwater contamination. Appropriate soil and water tests are being conducted to
confirm this.
After discovering the spill, and before we fully understood the areas affected or the extent
of the contamination, we notified the North Carolina State Emergency Response
Commission (SERC) and the Durham County Local Emergency Planning Committee
(LEPC) of the release. The LEPC dispatched representatives to investigate the release.
On May 8, 2012, we were advised by outside counsel that Airgas is responsible for
making any other reports required under applicable federal and state laws and regulations
because they are in charge of the facility and control the activity that resulted in the oil
spill.
On May 9, 2012, after reviewing our storm water permit, we realized that there was
reporting a requirement if the oil spill "may endanger health or the environment." While

Mr. Danny Smith, Surface Water Supervisor
N.C. Division of Water Quality, Raleigh Regional Office
May 11, 2012
Page 2
we do not believe that the oil spill has endangered health or the environment, we made a
verbal report to you out of an abundance of caution and to provide you with an
opportunity to visit the site to see the remediation efforts. .
Although we originally believed and reported to the SERC and LEPC that approximately
fifty gallons of oil were released, we now are confident that the total amount of oil
released was closer to 35 gallons. Further, we are planning to notify SERC and LEPC in
writing that this incident is not subject to EPRCRA reporting requirements based on the
exemption provided in 40 CFR 355.31 for "arty release that results in exposure to persons
solely within the boundaries of your facility."
REMEDIATION ACTIVITIES
Upon learning of the release on May 7, 2012, Airgas immediately dispatched its
emergency response contractor, Hepaco, to initiate clean-up of the spilled material.
Airgas is managing all remediation activities through Hepaco. Remediation activities
have included excavation and disposal of potentially contaminated soils, pressure
washing of contaminated surfaces with collection of wash waters, and soil and water
sampling to delineate the extent of the contamination.
These activates should be completed on May 11, 2012, pending the results of soil and
water sampling. If sampling indicates additional contamination, remediation activities
will be restarted until all contamination has been removed.
PREVENTATIVE ACTIONS
Upon completion of remediation activities, Cree will meet with Airgas to discuss and
implement appropriate preventative actions.
Should you have any questions or need additional information, please feel free to contact
Quinton Hancock at 919-313-5845.

Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 31, 2002. The Division staff is currently in the process ofrewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of -your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250,00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the I I categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e: the facilty industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://h2o.enr.state,nc.us/su/storinwater.htm]
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed

Dear Mr. Hancock:
The Division of Water Quality received your request for changes in your representative outfall status
(granted July 26, 2007) at your Durham facility on November 6, 2008. Based on our understanding of
your representations of current site drainage conditions as presented in your letter, attachments, and site
visit November 18, 2008, we are granting the following revision to your monitoring obligations under
NCG030433, Please maintain a copy of this letter on file at the facility.

RE: SPW3 inspection for RTP and Durham sites response - NPDES Number NCG030433 and
NCG030541
Dear Mr. Parnell;
Thank you for the storm water inspection and review of our records at the RTP and Durham sites on April
8, 2014. Both Donna and I enjoyed visiting with you; your comments regarding both sites will be very
helpful as we go forward with our spw3 programs.
There were two action items to address as a result of the inspections; documentation of annual spw3 plan
review, and documented specific training for each plan.
- Stormwater plan requires annual review — Please find attached documents certifying that both
the RTP and Durham site plans were reviewed and updated.
- Stormwater specific training for both sites — At the time of the inspection, Cree presented an
updated spw3 training module for both sites, and has now implemented this module into electronic
format for computer based training (OLMS). All affected individuals will be assigned the training
with a due date before May 30, 2014. Documentation that the training is complete for these
individuals will be sent to your attention by May 30, 2014.
Thanks again for the opportunity to address these issues as we continue to refine and improve our spw3
programs.
Best regards -
a

Re: Cree, Inc.; Report of Non-Stormwater Discharge Incident (COC NCG030433)
Dear Mr. Schuster:
Please find enclosed a Report of Non-Stormwater Discharge Incident for the Cree, Inc. (Cree)
facility located at 4600 Silicon Drive, Durham, NC 27703. The enclosed report has been
prepared on behalf of Cree by Piedmont Geologic. The report supplements the initial notification
that Cree submitted to the Division of Water Quality on September 1, 2004. .
The enclosed report summarizes a comprehensive investigation that Cree has undertaken in
response to the discovery of an unintentional discharge of process wastewater through a storm
drain system. Cree has identified the cause of the wastewater discharge and made immediate
changes to stop the discharge. Cree has also upgraded its facility maintenance schedule and
operational procedures to avoid the recurrence of the same discharge scenario. finally, Cree
intends to continue the sampling and analysis program described in the report to verify that
mitigation of the discharge has occurred.
We trust that you will find Cree's voluntary and comprehensive reporting and corrective actions
to be consistent with the company's traditional proactive approach to environmental compliance.
Cree welcomes the opportunity to discuss this matter further with you and your staff. If you have
questions or require additional information, please contact me at 919.313.5389 or

' Deport of Non-Stormwater Discharge Incident
Cree, Inc., Durham, North Carolina
' October 22, 2004
1.0 INTRODUCTION AND EXECUTIVE SUMMARY
' This document presents a report regarding a non-stormwater discharge that was discovered at the Cree, Inc. facility,
1 located at 4600 Silicon Drive in Durham, North Carolina in August 2004. The report serves as a follow-up to the
letter from Cree to the North Carolina Department of Environment and Natural Resources (NCDENR), Division of
Water Quality (DWQ), dated September 1, 2004, a copy of which is provided in Appendix A. The Cree facility has
' been issued Certificate of Coverage (COC) NCG030433 under the NPDES Stormwater Permit program.
The site location is shown in Figure 1 and the site layout is shown in Figure 2. On August 26, 2004, Cree personnel
discovered the presence of process wastewater from Building 5 in the combined foundation/storm drain (a.k.a. the
foundation drain) that contributes to facility stormwater discharge outfall no. 4 (Figure 2). Investigative activities
initially indicated that the probable source of the discharge was a process wastewater sump located in Building 5.
' Deteriorated piping grout in the sump allowed leakage of process wastewater into a sulg,ade foundation drain
beneath Building 5 that ties into the stormwater drainage system leading to stormwater discharge outfall no. 4.
Following discovery of this condition, the Building 5 sump was repaired and sealed/waterproofed. Subsequent
' hydrostatic testing of the Building 5 sump indicated no additional leakage.
' As a precautionary measure, the remaining facility sumps were also sealed and waterproofed on September 1, 2004.
During this activity, deteriorated concrete in the base of a process wastewater receiving basin in Building 5 was
' discovered. Hydrostatic testing indicated leakage from the Building 5 receiving basin and, in response, the receiving
basin was decommissioned.
' Based on observed process wastewater levels in the Building 5 sump, it is estimated that the sump leak occurred over
a 33 day period between July 24 and August 26, 2004. The duration of the Building 5 receiving basin leak is
unknown. The Building 5 receiving basin began operating in July 2003; therefore, the receiving basin leak began at
some time between July 2003 and September 2004.
1 Based on laboratory analysis of August and September 2004 process wastewater and foundation drain samples,
acetone, 1-methyl 2-pyrrolidinone (NNIP), boron, chloride, and fluoride were identified as potential constituents of
concern (COCs) in the process wastewater discharge. Results of laboratory analysis of September and October
foundation drain samples, collected following repair of the Building 5 sump and decommissioning of the Building 5
' receiving basin, indicate steady reductions in COC concentrations in the foundation drain water following
completion of these activities.
To evaluate potential environmental impacts from the previous discharge of process wastewater into the foundation
' drain, water samples were collected for laboratory analysis from stormwater discharge outfall no. 4 and two

downstream creek locations in October 2004. Of the process wastewater and foundation drain COCs, only boron,
chloride, and fluoride were detected in the samples from outfall no. 4 and the downstream creek. The detected
fluoride concentration in the stormwater discharge outfall sample was above the North Carolina water quality
standard under 15A NCAC 213, whereas the detected chloride concentration in the outfalI no. 4 sample was below
the water quality standard (boron does not have a published water quality standard). Detected concentrations of
chloride and fluoride in the downstream creek samples were below the State water quality standards.
Based on the results of site assessment activities, additional facility Best Management Practices (BMP) are being
adopted by Cree. These practices include annual inspections and leak testing of process wastewater receiving basins
and sumps, and implementation of an augmented waste management program. Monthly sampling/analysis of
foundation drain, outfall, and downstream creek samples will be performed over a one year period to verify
mitigation of the previous COC discharges. Following one year of monitoring, recommendations will be made for
cessation of monitoring, modification of BMPs, and/or other corrective actions, if necessary.

SITE DESCRIPTION
Report of Non-Stormwater Discharge Incident
Cree, Inc., Durham, North Carolina
October 22, 2004
' The Cree microelectronics manufacturing facility is located on a 30.263 acre tract at the corner of Chin -Page Road
' and Silicon Drive in Durham, North Carolina (Figure 1). The facility was constructed in 1986. Cree did not occupy
the site until 1998.
' A facility map is provided as Figure 2. The facility is developed with a two story main production facility (Building
I and 5), packaging and test facility (Building 2, 3, and 7), service facility (Building 4), shipping/receiving and
boilers facility (Building 6), raw material storage building, fire pump house, process water backup building, two
process chilled water buildings, a hazardous waste storage area, and various bulk gas storage locations.
' A map showing the facility stormwater drainage system is provided as Figure 2. Facility stormwater runoff is
conveyed via subsurface piping to five storm drain outfalls (denoted SDO-1 through SDO-5). Stormwater runoff
' from the outfalls drains to Stirrup Iron Creek, which borders the facility property to the west and northwest. Stirrup
Iron Creek is classified as Class C NSW (nutrient sensitive water) surface water by NCDENR. Stirrup iron Creek is
' located within the Neuse River basin.
Stormwater discharge outfall no. 4 (SD04), a subject of this report, is located at the southwest corner of the facility.
SD04 forms the headwaters of a small unnamed creek that flows into Stirrup Iron Creek over a distance of
' approximately 225 feet.
A map showing the Building 5 process wastewater system is provided as Figure 3. Process wastewater primarily
includes aqueous mixtures of acids, alcohols, peroxides, and metal oxides. Process wastewater is routed through a
series of receiving basins, process sumps, and piping to a centralized onsite wastewater collection system prior to
' discharge to the public sanitary sewer system under Durham County Industrial User Permit No. DC-030.
According to facility personnel, a spring was discovered in the area intended for Building 5 during construction
activities in early 2000. In response, a foundation drain system, consisting of perforated pipes, drainage matting, and
crushed rock fill, was installed to relieve hydrostatic pressure on the building Foundation. The as -built layout of the
' drainage system is unknown, but it is believed that the foundation drain system runs northeast to southwest beneath
Building 5. The foundation drain system ties into a single drain pipe at the southwest corner of Building 5, which
' then ties into the stormwater drain system for Building 6 at a point between Building 5 and 6 (Figure 2). The
combined foundation/storm drain then flows to SDO-4, receiving contributory flow from other stormwater drains for
' Building 5. Water has been observed to flow from the Building 5 foundation drain during rainfall events and up to a
few days directly following rainfall events. An average flow rate of approximately '/. gallons per minute (gpm) was
recently observed by Cree in the foundation drain during non-stormwater conditions_

3.0 DESCRIPTION OF NON-STORMWATER DISCHARGE INCIDENT
3.1 Non-Stormwater Discharge Scenario
' According to Cree, on August 26, 2004, a foul odor of unknown origin was detected by Cree personnel coming from
the foundation drain. A camera survey of the foundation drain revealed the presence of debris in the line, indicating
a potential leak in the process wastewater lines associated with Building 5. Dye was added to the Building 5 process
wastewater sump (approximately 6 ft. x 6 ft. in area and 8 ft. deep) and traced to the Building 5 combined
' foundation/storm drain. This result confirmed the existence of a pathway for process wastewater to travel from the
wastewater collection system to the foundation drain, further camera inspection of Building 5 wastewater lines
' indicated a stressed pipeline joint at the exterior of the southwest wall of Building 5, which was uncovered for
further investigation. Upon physical inspection, no problems with the pipeline joint were found, but prior to re-
burying the pipe, the joint was resealed and encased in concrete.
Following the August 26, 2004 pipe joint repairs, Cree added dye to the Building 5 sump a second time, and again
' the dye was observed in the combined foundation/storm drain. In response, the contents of the sump were pumped
down and rerouted to the process wastewater drain located in Building 6. Once the sump was empty, visible
deterioration of the concrete was found on the north wall below one of two incoming process wastewater pipes (see
photograph in Appendix B). The sump was cleaned by an outside contractor, and Cree personnel entered the sump
to inspect the sleeves of the two incoming process wastewater pipes - one located on the north wall and the other on
the east wall. The sleeve of the pipe in the north wall was tight with no leakage. However, the grout surrounding the
incoming pipe in the east wall of the sump appeared thin and deteriorated (Figure 5). Based on these findings, it was
determined that process wastewater leaked from the Building 5 sump and into the Building 5 foundation drain.
' In response to the above findings, the Building 5 sump was taken offline on August 26, 2004. Process wastewater
was temporarily re-routed into collection totes and transferred to the Building 6 process wastewater drain. Next, on
' August 29, 2004, two wastewater pipe penetrations into the sump were cored, pipe sleeves were installed and
grouted with a chemical resistant epoxy. Finally, waterproof sealant was applied to the walls and the floor of the
sump (Appendix B).
On August 31, 2004, following curing of the sump epoxy and sealant, the Building 5 sump was filled with water,
' with dye added. The water level in the sump was not observed to change over a 24 hour period, and no dye was
observed in the foundation drain. Based on these results, the previous process wastewater leak was eliminated.
' To prevent a similar occurrence as described above, Cree retained an outside contractor on September 1, 2004 to
inspect and clean all facility process wastewater sumps and to apply epoxy coats. During these activities, a receiving
7

' October 22, 2004
basin (approximately 2 ft. x 2 ft. in area and I ft. deep) in the Building 5 basement was found to have honeycombed
deterioration of the bottom of the basin, which originally consisted of a 4 inch thick concrete pad. The concrete pad
deterioration was caused by dilute inorganic components in the process wastewater stream. Based on the condition of
the receiving basin, it was determined that leakage of process wastewater from the Building 5 receiving basin into
the foundation drain may have occurred. The Building 5 receiving basin was decommissioned on September 1, 2004
pending repairs. Under normal operating conditions, process wastewater from the Building 5 receiving basin should
have flowed into the Building 5 sump (Figure 3).
3.2 Non-Stormwater Discharge Duration and Quantity
According to Cree, it is estimated that the process wastewater leakage from the Building 5 sump occurred over an
approximate 33 day period, from the time of conclusion of maintenance activities on July 24, 2004 to the time of
leak discovery on August 26, 2004. This is based on the fact that wastewater levels in the sump were never observed
' at or above the level of the influent pipes prior to the July 2004 maintenance activities.
Typical total process wastewater discharge rates from the Building 5 sump were measured by Cree in September
2004 and found to range from 6 gallons per minute (gpm) to 13 gpm (typical maximum rate for all flows to the
sump). Approximately 35% of the wastewater flow is steam condensate or dehumidification water. The remaining
65% is process wastewater containing low concentrations of various process chemicals and the discharge solution
from two thermal processing units (TPU).
The Building 5 receiving basin originally began operating in July 2003; therefore, leakage of process wastewater
1 from the receiving basin started between July 2003 and the leak discovery on September 1, 2004. The rate of
disintegration of the concrete base of the receiver basin is unknown. As a result, the exact duration of the leak from
the receiving basin cannot be determined. The average flow rate of process wastewater into the Building 5 receiving
basin (i.e., prior to decommissioning) was measured by Cree in September 2004 to be approximately 3 gallons per
' minute (gpm).

4.0 FACILITY MEDIA SAMPLINGIANALYSIS METHODS AND RESULTS
4.1 Building 5 Process Wastewater
' in order to identify constituents of concern (COCs) in the process wastewater that leaked into the Building 5
foundation storm drain system, initial process wastewater samples were collected by Cree on September 2, 2004
' from the Building 5 sump ("B5-PW-WI") and the wastewater stream previously flowing to the Building 5 receiving
basin ("135-TPU-PW"). The samples were collected directly into laboratory containers and submitted under chain of
' custody to TriTest in Raleigh, North Carolina (State laboratory certification no. 067).
' Based on the production processes, the September 2, 2004 process wastewater sample from the Building 5 sump was
analyzed for the following.
' • Volatile organic by EPA Method 8260, with a library search For tentatively identified compounds;
• Priority pollutant metals by EPA Method 200.8;
1 • Chloride by EPA Method 340.2;
• Fluoride by EPA Method 325.2; and
' • pH by EPA Method 150.1.
' The September 2, 2004 process wastewater sample from the Building 5 receiving basin was analyzed only for boron
by EPA Method 200.8. This was done in anticipation of potentially using boron as a tracer for process wastewater
discharges to the foundation drain.
1
An additional process wastewater sample was collected by Piedmont Geologic from the Building 5 sump (B5-PW-
' WI) on October 5, 2004, following implementation of augmented facility waste management procedures (discussed
further below). The October 2004 process wastewater sample was submitted under chain of custody to STL
' Savannah, in Savannah, Georgia (State laboratory certification no. 269), and analyzed for the same parameters listed
above, with the exception that only boron was included in the metals analysis.

Following receipt of results of laboratory analysis of the September 2, 2004 process wastewater sample, Cree
investigated the sources of the detected concentrations of boron, acetone, chloroform, NMP, chloride, and fluoride.
Through a waste management audit, Cree identified errant waste management practices and equipment deficiencies
that were resulting in the introduction of process chemicals and byproducts, including acetone, photoresist, and
NMP, into process wastewater drains. In addition, it was discovered that breakages of the quartz baths used to

manage NMP were occurring on an approximately monthly basis, resulting in the introduction of NMP into process
' wastewater drains.
Upon discovery of the above conditions in September 2004, Cree immediately enacted equipment and procedural
' changes, with supporting personnel communications, to eliminate the inadvertent discharges. The equipment
changes included installation of a containment basin under each quartz bath to contain NMP spills resulting from
quartz bath failures. Procedural changes included informing production personnel of augmented waste management
and disposal practices. Results of laboratory analysis of the October 2004 process wastewater sample, following
Cree's corrective actions, indicated that COC concentrations decreased by at least two orders of magnitude.
4.2 Building 5 Receiving Basin Soil
Following the September 1, 2004 discovery of the deteriorated concrete in the Building 5 receiving basin, and the
' decommissioning of the receiving basin, as discussed in Section 3.1, soil samples were collected by Piedmont
Geologic from below the base of the basin on September 1, 2004. Soil samples were collected over 6 inch depth
' intervals, starting at the base of the receiving basin, to a depth of 24 inches below the base (see photograph in
Appendix B).
1 To evaluate baseline soil conditions, one soil sample was collected in an outlying grassy area at the northwest corner
of the Cree property (Figure 2). The background soil sample ("BG-1") was collected from a depth of approximately
i0-6 inches below the ground surface.
The soil samples were collected using a stainless steel hand auger that was decontaminated prior to use with a soap
and tap water wash and distilled water rinse. Upon collection, the soil samples were transferred directly to
' laboratory containers. The soil samples were stored on ice in a cooler and transferred under chain of custody to
Environmental Science Corp. in Mt. Juliet, Tennessee (State laboratory certification no, 375), and analyzed for the
following.
• Chloride and fluoride by EPA Method 9056;
• Boron, gold, nickel, and tin by EPA Method 601013;
• Iodide by Method ISE;
' . pH by EPA Method 9045C.
In addition, the shallowest and deepest soil samples from the receiving basin were analyzed for total organic halides
(TOX) by EPA Method 9023.

' Iodide and TOX were not detected in any of the soil samples. Chloride was detected in one soil sample from
beneath the receiving basin (12-18 inches), but at a concentration only slightly above the laboratory detection limit.
pH values for all the soil samples were within the normal range.
Fluoride, boron, and nickel were detected in all of the receiving basin soil samples as well as the background soil
sample. The detected concentrations of boron and nickel in the receiving basin soil samples are similar to the
detected concentrations in the background soil sample. The detected fluoride concentrations in the two shallowest
receiving basin soil samples (0-6 inches and 6-12 inches) are approximately 2.5 times the detected fluoride
concentration in the deeper receiving basin soil samples (12-18 inches and 18-24 inches) and the background soil
sample. Tin was detected in the shallowest sump soil sample, but was not detected in any of the deeper sump soil
1 samples or the background soil sample.
Gold was detected in all of the sump soil samples and the background soil sample. The detected gold concentrations
in the sump soil samples are substantially higher than the detected gold concentration in the background soil sample.
Detected gold concentrations decrease substantially with depth below the base of the sump.

' drain was collected by Cree on August 27, 2004. Fallowing repair of the Building 5 sump and decommissioning of
the Building 5 receiving basin, a second foundation drain sample was collected by Cree on September 2, 2004.
Following implementation of the augmented waste management procedures and changes discussed in Section 4.1, a
third foundation drain sample was collected by Piedmont Geologic on October 5, 2004.
' The foundation drain sampling point is shown in Figure 2. The sampling point is at the intersection where the
Building 5 foundation drain ties into the Building 6 stormwater drain. Due to the lack of rainfall around the time of
the sampling events, the August -October 2004 samples are representative of the foundation drainage only.
1 The foundation drain samples were collected directly into laboratory containers. The August 27, 2004 foundation
drain sample was submitted under chain of custody to TriTest and analyzed for the following.
• Volatile organics by EPA Method 8260;
• Titanium by EPA Method 200.8;
• Chloride by EPA Method 340.2;
• Fluoride by EPA Method 325.2; and
' • pH by EPA Method 150. l .
The September 2, 2004 foundation drain sample was submitted under chain of custody to TriTest and analyzed for
the same parameters listed above. In addition, the EPA Method 8260 analysis included a library search for
tentatively identified compounds, and the EPA Method 200.8 analysis included the full list of priority pollutant
' metals (excluding titanium).

' Report of Nan-Stormwater Discharge Incident
Cree, Inc., Durham, North Carolina
' October 22, 2004
' A substantial, order -of -magnitude, reduction in acetone concentration was observed between the August 27, 2004
foundation drain sampling event (prior to repair of the Building 5 sump and decommissioning of the Building 5
receiving basin) and the September 2, 2004 foundation drain sampling event (following completion of the remedial
work on the Building 5 sump and receiving basin). An additional 50% reduction in acetone concentration was
observed between the September 2 and October 5, 2004 foundation drain sampling events. Fluoride concentrations
' also decreased by approximately 50% between the September and October 2004 sampling events. NMP was
identified in the September 2004 foundation drain sample but was not identified in the October 2004 foundation
drain sample. Detected chloride concentrations remained relatively the same between the August to October 2004
foundation drain sampling events, and boron concentrations increased between the September and October 2004
foundation drain sampling events.
In summary, although COCs were detected in the most recent foundation drain sample (October 2004), the results
' reflect a substantial decrease in the concentration of most COCs following repair of the Building 5 sump and
decommissioning of the Building 5 receiving basin in August -September 2004. The recommended corrective actions
in Section 5.0 include monthly sampling and analysis of foundation drain samples to verify continued mitigation of
COC discharges.
4.4 Stormwater Discharge Outfall No. 4 and Downstream Creek
On October 5, 2004, water samples were collected by Piedmont Geologic from facility stormwater discharge outfall
no. 4 (SDO-4), and from the creek channel leading from SD04 to Stirrup Iron Creek. In conjunction with this
activity, sediment samples were collected by Piedmont Geologic from beneath each water sampling point. Sampling
locations are shown in Figure 2.
The outfall and creek samples were collected directly into laboratory containers. The sediment samples were
collected using a stainless steel trowel and transferred to laboratory containers. Prior to collecting each sediment
sample, the sampling trowel was cleaned with a soap and tap water wash and distilled water rinse. The outfalllereek
water and sediment samples were submitted under chain of custody to STL Savannah, and analyzed for the
following.
• Volatile organics by EPA Method 8260;
• Boron by EPA Method 601013;
• Chloride and Fluoride by EPA Method 9056; and
• pH by EPA Method 9045.

' For comparison purposes, State water quality standards for Class C NSW surface water (the applicable classification
for Stirrup Iron Creek) are listed in the above table.
Of the detected EPA Method 8260 compounds, chloromethane was detected in the outfall sample and farthest
downstream creek sample at concentrations of 4.0 ugfL and 4.7 ug/L, respectively. No published State water quality
' standard exists for chloromethane. Chloromethane was not detected in any of the August -October 2004 foundation
drain samples (Section 4.3), and is not known to be used in production at the facility. Therefore, the source of the
' detected chloromethane concentrations is unknown.
' Toluene was detected in sample Creek-], but not in the outfall sample upstream of Creek-1 or the Creek-2 sample
downstream of Creek-1. The detected toluene concentration in Creek -I (I.1 ug/L) is below the State water quality
standard (l I ugfL). Toluene was not detected in any of the August -October 2004 foundation drain samples (Section
4.3), and is not known to be used in production at the facility. Therefore, the source of the detected toluene
concentrations is unknown.
Acetone, which was detected in August -October 2004 process wastewater and foundation drain samples, was not
p p
1 detected in the October 2004 outfall and creek samples.
Chloride was detected in all three of the October 2004 outfall and creek samples, at concentrations well below the
State water quality standard. Boron was also detected in all three of the outfall and creek samples; however, there is
no published State water quality standard for boron. The detected chloride and boron concentrations decreased
' substantially between the outfall sample and downstream creek samples collected in October 2004.
L Fluoride was detected in the October 2004 outfall sample at a concentration (6.0 mg/L) above the State water quality
standard (1.8 mg/L). Fluoride was detected in sample Creek-], directly downstream of SDO-4, at a concentration
(0.56 ug/L) below the State water quality standard, and fluoride was not detected in the farthest downstream creek
sample (Creek-2).
In summary, fluoride concentrations above the State water quality standard were detected in the October 2004 water
sample from SDO-4. However, detected fluoride concentrations were below the State water quality standard in the
' downstream creek samples collected in October 2004. The recommended corrective actions in Section 5.0 include
monthly sampling and analysis of outfall and creek samples to verify continued mitigation of COC discharges.

5.0 CONCLUSIONS AND RECOMMENDATIONS
rBased on the results of the site assessment activities described above, the following conclusions have been reached
regarding potential environmental impacts from the process wastewater discharge incident.
r
• A leak of process wastewater from a Building 5 sump into the Building 5 foundation drain was discovered
'
on August 26, 2004. The Building 5 sump was taken offiine on August 26, 2004. The sump leak was
caused by deteriorated sump piping grout, which was repaired on August 29, 2004. The sump tested tight
'
and was put back online on August 31, 2004.
• The Building 5 sump leak is believed to have occurred over a 33 day period from July 24 to August 26,
2004.
• A leak of process wastewater from a Building 5 receiving basin into the Building 5 foundation drain was
discovered on September I, 2004. The Building 5 receiving basin was decommissioned on September 1,
2004 inspected. The basin leak by deteriorated in basin
and receiving was caused concrete the of the
receiving basin.
+ The Building 5 receiving basin leak started at some point after the receiving basin began operating in July
2003.
• Laboratory analysis of a foundation drain sample collected on August 27, 2004 indicated concentrations of
acetone, fluoride, and boron. Detected concentrations of acetone and fluoride were significantly lower in
foundation drain samples collected on September 2 and October 5, 2004 following repair of the Building 5
sump and decommissioning of the Building 5 receiving basin.
• Laboratory analysis of process wastewater samples collected in September 2004 indicated that acetone,
'
NMI', boron, chloride, and fluoride were dissolved COCs in the wastewater stream that were released to the
Building 5 foundation drain.
'
• Fluoride was detected at a concentration above the North Carolina water quality standard in an October
2004 water sample from SD04. Fluoride was not detected in downstream creek samples at concentrations
'
above the water quality standard.
• Fluoride and gold were detected at elevated concentrations in soils directly beneath the base of the Building
5 receiving basin. Fluoride concentrations above background are confined to the uppermost 12 inches of
soil below the basin.
rBased on the conclusions listed above, the following additional Best Management Practices (BMPs) are being
adopted by Cree.

' October 22, 2004
• Following the August -September 2004 facility sump repairs and sealing/waterproofing effort, facility
receiving basins and sumps will be inspected and hydrostatically tested for leaks on an annual basis.
• Augmented waste management procedures are being adopted and reinforced through a vigorous
communications effort with Cree personnel to minimize/eliminate introduction of acetone, photoresist,
NMP, chloride, and fluoride into the process wastewater stream.
• Quarterly audits of augmented waste management practices will be conducted to ensure compliance with the
' reinforced facility waste management procedures and equipment changes discussed in Section 4.1.
' Monthly sampling/analysis of water samples collected from the foundation drain, SD04, and the two downstream
creek locations sampled previously will be performed to verify mitigation of the previous COC discharges.
Following one year of monitoring, Cree will determine whether cessation of monitoring, modification of BMPs,
and/or other corrective actions are appropriate.

for precision.
1 Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
unless qualified as 'R' (Rejected).
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
' Control Limits (AW (SS)
2-Fluorophenol 31-119 Nitrobenzene-d5 43-118 Dibromfluoromethane 79-126 83-119
Phenol-d5 12-134 2-Fluorobiphenyl 45-128 Toluene-d8 81-114 82-116
2,4,6-Tribromophenol 51-141 Terphenyl-d14 43-137 4-Bromofluorobenzene 65-129 72-126
' TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

L168292
RSC Level 2 Data Package
The data package includes a summary of the analytic results of the quality
control samples required by the SW-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
' any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a 11J4" qualifier for ail effected samples.
Matrix Spike and Matrix Spike Duplicate. - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
' also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a 11J5" or a "J611. The relative percent difference (%RPD)
' between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected samples are flagged with a ,j3n qualifier.

Data Qualifiers
'
Inorganic Data
B
The reported result is an estimated concentration that is less than the PQL, but greater than or
equal to the MDL.
'
E
The reported value is an estimated because of the presence of matrix interference.
N
The matrix space recovery is not within control limits. See case narrative.
'
S
U
The result was determined by Method of Standard Addition (MSA).
The compound was analyzed for, but was not detected at or above the MDLJPQL.
<
The compound was analyzed for, bun was not detected at or above the PQL.
W
The post -digestion space for fimiace AA analysis was out of control limits, while sample
absorbance was less than 50% of space absorbance.
'
*
Duplicate analysis is not within control limits.
Organic Data
B
The analyte was found in the associated -method blank
D
The reported result is from a Secondary dilution
*F33
Control limits are established only for surrogate concentration levels specified by EPA methods.
'
Because the sample was diluted prior to analysis, surrogate recoveries are not reported.
E
The reported result exceeded the calibration range of the instrument.
I
The reported result is an estimated concentration that is less than the PQL, but greater than or
equal to the MDL.
'
P
The GC or BPLC confirmation criteria was exceeded_ The relative percent difference is greater
than 40% between the two GC columns or HPLC detectors.
U
The compound was analyzed for, but was not detected at or above the MDL TQL.
'
<
The compound was analyzed for but was not detected at or above the PQL.
*F53
Because surrogate recoveries were outside established limits the sample was re -extracted and/or
reanalyzed. Comparable results were obtained_
*F54
Because surrogate recoveries were outside established limits, the sample was re -extracted and/or
'
reanalyzed. Both sets of data are provided.
*F36
Surrogate recovery was outside of established limits due to a coeluting matrix interference present
in the sample.
'
X1
Internal standards recovered outside of advisory limits.
X
Surrogate recovery was outside of advisory limits.
Y
Spike recovery was outside of advisory limits.
Universal
*F61
The recoveries of the matrix spaces are outside advisory limits due to the abundance of the target
anatyte in the sample.
*F65
Elevated detection limits were reported due to sample matrix interference which required sample
or extract dilution.
*F73
Matrix spilce recoveries were outside advisory limits due to matrix interference present in the
sample.
*F82
Insufficient sample volume was available to perform batch specific matrix spikes.
The test results in this report meet all NELAP requirements for parameters for which accreditation is
required or available. Any exceptions to NELAP requirements are noted in this report. Pursuant to NELAP,
